DESCRIPTION OF EMBODIMENTS

The following describes technical solutions of this application with reference to accompanying drawings.

FIG. 1 is a schematic diagram of a conventional system for implementing an automobile electronic control function. As shown in FIG. 1 , the system 100 for implementing the automobile electronic control function includes a CCP 110, n DCs 120, and m automobile parts 130, where n and m are positive integers.

The CCP 110 is in communication connection with the n DCs, and may receive data sent by the DCs, or send control information to the DCs. The CCP 110 may be understood as a general platform for automobile electronic control and information processing. Distributed computing and control systems (for example, ECUs or DCs) in the automobile are optimized and integrated to implement network-based and integrated control and management of functional modules of automobile computing, control, and communication, and maximize real-time sharing of software and hardware resources, such as automobile computing and control.

Each DC 120 is configured to manage a functional domain in the automobile, in other words, the DC is in communication connection with a plurality of automobile parts located in a functional domain. The DC 120 is configured to control an automobile part in a corresponding functional domain, or provide a data processing function for an automobile part in a corresponding functional domain.

Functional domains are usually classified based on functions of automobile parts in the automobile, and each functional domain has an independent domain controller, namely, a DC. Generally, the DC in an automobile may include a self-driving domain controller, a CDC, a vehicle domain controller (VDC), and the like.

The self-driving domain controller is configured to provide services for automobile parts in an intelligent driving domain. The automobile parts in the intelligent driving domain include a monocular camera lens, a binocular camera lens, a millimeter-wave radar, a lidar, an ultrasonic radar, and the like.

It should be noted that a function of the foregoing self-driving domain controller may be implemented by a mobile data center (MDC).

The CDC is configured to provide a service for automobile parts in a cockpit domain. The automobile parts in the cockpit domain include a head-up display, an instrument display, a radio, navigation, a surround camera lens, and the like.

The VDC is configured to provide a service for automobile parts in a vehicle body domain and automobile parts in a chassis domain. The automobile parts in the vehicle body domain include a door/window lifting controller, an electric rearview mirror, an air conditioner, a central door lock, and the like. The automobile parts in the chassis domain include an automobile part in a braking system, an automobile part in a steering system, a throttle, and the like.

An automobile part 130 may specifically include an ECU 131 and an execution element 132. For example, the automobile part 130 may be a sensor or an actuator in the automobile.

The ECU 131 is located in the automobile part, and is configured to provide electronic control functions for the automobile part. For example, the ECU 131 is an ECU in a rain wiper, an ECU located in an automobile door, and the like.

The electronic control functions mainly include a logic control function and a data processing function. The logic control function includes controlling, based on the obtained control information, the automobile part to perform an operation, for example, controlling an action of the rain wiper based on the control information, for another example, controlling an on/off state of a door lock on the automobile door based on the control information. The data processing function includes processing to-be-processed data in the automobile part. For example, the data processing function includes performing data fusion on weather information collected by using a sensible element of the rain wiper and running data of the rain wiper. For another example, the data processing function includes performing data fusion on fingerprint information obtained by using a sensible element of the door lock on the automobile door and on/off state information of the automobile door.

It should be noted that, unless otherwise specified, the ECU in this embodiment of this application refers to an electronic control element located in the automobile part, and is different from an “electronic control unit” (also referred to as an engine control unit) in other approaches. The engine control unit is located outside a plurality of automobile parts in an engine system, is configured to control the plurality of automobile parts in the engine system, and may be considered as an independent centralized controller. However, the ECU in this embodiment of this application, namely, an “ECU” below, indicates an ECU located in the automobile part. For example, the ECU may be ECUs located in the plurality of automobile parts in the engine system.

It should be noted that FIG. 1 shows only a possible implementation of a system for implementing an automobile electronic control function, and a conventional system for implementing an automobile electronic control function may have another variation. For example, FIG. 2 shows another system for implementing an automobile electronic control function, to be specific, the automobile part 130 no longer performs a communication connection with the CCP 110 by using the DC 120, but may directly perform a communication connection with the CCP 110.

It should be understood that, in the system for implementing the automobile electronic control function shown in FIG. 2 , functions of components such as an automobile part and a CCP are similar to or the same as functions of components such as the automobile part and the CCP shown in FIG. 1 . For brevity, details are not described herein again.

Either in the system that is for implementing the automobile electronic control function and that is shown in FIG. 1 or the system that is for implementing the automobile electronic control function and that is shown in FIG. 2 , to implement electronization of the automobile and meet requirements for implementing various functions of the automobile, each automobile part has an independent ECU. The manner in which ECUs are distributively arranged results in higher costs of the automobile parts.

Besides, in the foregoing manner in which the ECUs are distributively arranged, a length of a harness used for communication between an ECU and a DC and a length of a harness used for communication between an ECU and a CCP in the system for implementing the automobile electronic control function are relatively large. This results in relatively high costs of the system for implementing the automobile electronic control function.

To avoid the foregoing problem, this application proposes a new system for implementing an automobile electronic control function, to be specific, a VIU is added to the system for implementing the automobile electronic control function. The VIU provides part or all of the data processing or control functions for the plurality of automobile parts. In this way, in a solution in which one VIU serves the plurality of automobile parts, an ECU in each automobile part does not need to implement the foregoing data processing function or control function in the conventional system for implementing the automobile electronic control function. This helps reduce costs of the automobile parts.

In another aspect, in the system for implementing the automobile electronic control function provided in this application, the plurality of automobile parts may be connected to one VIU, and connected to a DC or a CCP by using the VIU. Therefore, each automobile part in the conventional system for implementing the automobile electronic control function does not need to be connected to a DC or a CCP by using a respective harness, and this helps reduce the length of the harness in the system for implementing the automobile electronic control function. The following describes, with reference to FIG. 3 and FIG. 4 , schematic diagrams of systems for implementing an automobile electronic control function according to this application. A system 300 for implementing an automobile electronic control function shown in FIG. 3 may be understood as an improvement on the system 100 for implementing the automobile electronic control function shown in FIG. 1 . A system 400 for implementing an automobile electronic control function shown in FIG. 4 may be understood as an improvement on the system 200 for implementing the automobile electronic control function shown in FIG. 2 .

It should be noted that, in the embodiments of this application, the system for implementing the automobile electronic control function may be applied to an intelligent automobile, a new energy automobile, a conventional automobile, or the like. New energy automobiles include a pure electric automobile, an extended-range electric automobile, a hybrid electric automobile, a fuel cell electric automobile, a hydrogen engine automobile, or another new energy automobile. Conventional automobiles include a gasoline automobile, a diesel automobile, and the like. This is not limited in the embodiments of this application.

FIG. 3 is a schematic diagram of a system for implementing an automobile electronic control function according to an embodiment of this application. It should be understood that units that have a same function in the system that is for implementing the automobile electronic control function and that is shown in FIG. 3 and the system that is for implementing the automobile electronic control function and that is shown in FIG. 1 use a same number. For brevity, details are not described herein.

The system 300 for implementing the automobile electronic control function shown in FIG. 3 includes a CCP 110, n DCs 120, m automobile parts 310, and b VIU 320, where b, n, and m are positive integers.

The automobile part 310 may include one or more of the following automobile parts an automobile part having some or all functions of ECUs, and an automobile part without the electronic control function.

It may be understood that the automobile part 310 having all the electronic control functions is the same as the automobile part 130 in FIG. 1 .

It may be understood that the automobile part 310 having some of electronic control functions has fewer electronic control functions than the automobile part 130 in FIG. 1 .

It may be understood that the automobile part 310 without some of the electronic control functions is the automobile part 310 without an ECU.

The VIU 320 is in communication connection with the plurality of automobile parts 310, and is in communication connection with the DC in the automobile. For example, in FIG. 3 , the VIU 1 is in communication connection with an automobile part 1, an automobile part 2, and an automobile part 3, and the VIU 1 is in communication connection with a DC 1 and a DC 2.

It should be noted that the communication connection may be understood as a wireless connection or a wired connection for information exchange. This is not limited in this embodiment of this application. It may be understood that the wireless connection is that the VIU does not need to communicate with another unit in the automobile through a bus. For example, BLUETOOTH communication, or WI-FI communication may be used. It may be understood that the wired connection is that the VIU communicates with another unit in the automobile based on the bus. For example, a controller area network (CAN) bus, a local interconnect network (LIN) bus, or an Ethernet communications technology may be used.

Optionally, the VIU may be in communication connection with a DC in the automobile. For example, a VIU b is in communication connection with a DC n shown in FIG. 3 . The VIU may further be in communication connection with a plurality of DCs in the automobile. For example, a VIU 1 shown in FIG. 4 may be in communication connection with the DC 1 and the DC 2.

In the conventional system for implementing the automobile electronic control function, one DC usually communicates with a plurality of automobile parts in one functional domain. As shown in FIG. 1 , the DC 1 may be in communication connection with an automobile part 1 and an automobile part 2 in a functional domain 1. To be compatible with the conventional system for implementing the automobile electronic control function, a plurality of automobile parts belonging to one functional domain and a DC corresponding to the functional domain usually communicate with one VIU, so that the DC can control all automobile parts by using one VIU. This reduces changes to the conventional electronic control function system.

Optionally, one VIU may serve any functional domain in the automobile. For example, in the system 300 for implementing the automobile electronic control function shown in FIG. 3 , the automobile part 1 and the automobile part 2 that have the communication connection with the VIU 1 belong to a same functional domain, namely, the functional domain 1. In addition, the DC 1 that is in communication connection with the VIU 1 is a DC corresponding to the functional domain 1.

The functional domain served by the VIU may be a vehicle domain. In this case, the VIU may be in communication connection with a VDC, an automobile part in a vehicle body domain, and an automobile part in a chassis domain. The functional domain served by the VIU may be a cockpit domain. In this case, the VIU may be in communication connection with a CDC and an automobile part in the cockpit domain. Alternatively, the functional domain served by the VIU may be an intelligent driving domain. In this case, the VIU may be in communication connection with an MDC and an automobile part in the intelligent driving domain.

Optionally, one VIU may also serve a plurality of functional domains. In other words, the VIU is in communication connection with automobile parts in the plurality of functional domains and DCs. For example, in the system 300 for implementing the automobile electronic control function shown in FIG. 3 , the DC 1 is a DC in the functional domain 1, the DC 2 is a DC in a functional domain 2, automobile parts in the functional domain 1 include the automobile part 1 and the automobile part 2, and an automobile part in the functional domain 2 is the automobile part 3. The VIU 1 is in communication connection with the DC 1 and the DC 2. In addition, the VIU 1 is also in communication connection with the automobile parts in the functional domain 1 and the automobile part in the functional domain 2.

The VIU may provide services for two functional domains. In other words, the VIU is in communication connection with automobile parts in the two functional domains and the DCs. The two functional domains may be any two functional domains in the automobile. For example, the foregoing two functional domains may be the vehicle domain and the cockpit domain. In this case, the DCs that are in communication connection with the VIU are the VDC and the CDC. Correspondingly, the automobile parts that are in communication connection with the VIU are the automobile parts in the vehicle body domain, the automobile parts in the chassis domain, and the automobile parts in the cockpit domain.

For another example, the foregoing two functional domains may be the vehicle domain and a MDC. In this case, the DCs that are in communication connection with the VIU are the VDC and the MDC. Correspondingly, the automobile parts that are in communication connection with the VIU are the automobile parts in the vehicle body domain, the automobile parts in the chassis domain, and the automobile parts in the intelligent driving domain.

For another example, the foregoing two functional domains may be the cockpit domain and a MDC. In this case, the DCs that are in communication connection with the VIU are the CDC and the MDC. Correspondingly, the automobile parts that are in communication connection with the VIU are the automobile parts in the cockpit domain and the automobile parts in the intelligent driving domain.

The VIU may provide services for three functional domains. In other words, the VIU is in communication connection with automobile parts in the three functional domains and the DCs. For example, the three functional domains may be the vehicle domain, the cockpit domain, and a self-driving domain. In this case, the DCs that are in communication connection with the VIU are the VDC, the CDC, and the MDC. Correspondingly, the automobile parts that are in communication connection with the VIU are the automobile parts in the vehicle body domain, the automobile parts in the chassis domain, the automobile parts in the cockpit domain, and the automobile parts in the intelligent driving domain.

Certainly, if a conventional electronic function control architecture is not considered, there are many connection manners between the VIU and the automobile part and between the VIU and the DC. This is not limited in this embodiment of this application. For example, a DC corresponding to a functional domain and an automobile part in the functional domain may be connected to different VIUs. For another example, the VIU is in communication connection with only some automobile parts in a functional domain. For another example, an automobile part served by the VIU may have no relationship with a functional domain. The automobile parts served by each VIU may be determined based on other factors such as a physical position of an automobile part in the automobile.

FIG. 4 is a schematic diagram of a system for implementing an automobile electronic control function according to another embodiment of this application. It should be understood that units that have a same function in the system 400 that is for implementing the automobile electronic control function and that is shown in FIG. 4 and the system 100 that is for implementing the automobile electronic control function and that is shown in FIG. 1 use a same number.

The VIU 420 is in communication connection with a plurality of automobile parts 410, and is in communication connection with the CCP 110 in the automobile. For example, in FIG. 4 , a VIU 1 is in communication connection with an automobile part 1, an automobile part 2, and an automobile part 3, and the VIU 1 is in communication connection with the CCP 110.

It should be noted that the communication connection may be understood as a wireless connection or a wired connection. This is not limited in this embodiment of this application. It may be understood that the wireless connection is that the VIU does not need to communicate with another unit in the automobile through a bus. For example, BLUETOOTH communication, or WI-FI communication may be used. It may be understood that the wired connection is that the VIU communicates with the another unit in the automobile based on the bus. For example, a CAN bus, a LIN bus, or an Ethernet communications technology may be used.

Optionally, the VIU may provide services for all or some of the automobile parts in the automobile. When the VIU provides the service for some automobile parts, another automobile part that is in the automobile and that is not in communication connection with the VIU may directly communicate with the CCP, or may communicate with the CCP by using another VIU. This is not limited in this embodiment of this application.

When an automobile includes a plurality of VIUs, different VIUs in the plurality of VIUs may provide services for different automobile parts, or different VIUs in the plurality of VIUs may provide services for at least partially same automobile parts.

It should be noted that, in this embodiment of this application, a quantity of the plurality of VIUs included in the automobile is not specifically limited, for example, may be 2, 3, 4, or 5.

To improve flexibility and reliability of information (including data or control information) transmission in the system for implementing the automobile electronic control function, the plurality of VIUs may communicate with each other. A specific communication manner may be a bus-based communication manner. For example, the VIU communicates with another VIU in the automobile based on the CAN bus. For another example, the VIU communicates with another VIU in the automobile based on the LIN bus. For another example, the VIU communicates with another VIU in the automobile based on a high-speed communication protocol.

This is not specifically limited in this embodiment of this application.

FIG. 9 is a flowchart of a data processing method according to an embodiment of this application. It should be understood that the method shown in FIG. 9 may be performed by any VIU in the system 300 for implementing the automobile electronic control function, and is referred to as a “first VIU” below. The method shown in FIG. 9 includes a step 910 and a step 920.

910. The first VIU is configured to obtain first data of a plurality of automobile parts.

The backup function mainly includes replacing the first VIU to provide a data processing function for the plurality of automobile parts. The third VIU may be a VIU that is in the electronic function control architecture 300 and that is specially configured to provide the backup function, in other words, the third VIU generally does not provide the data processing service for the automobile parts. When a VIU (for example, the first VIU) in the electronic function control architecture 400 fails, the third VIU may replace the first VIU to provide the data processing function for the plurality of automobile parts.

To improve flexibility of data transmission in the electronic control architecture, the first VIU may be in communication connection with a plurality of DCs, in other words, the first VIU is further configured to send the first data to a second DC.

In other words, after obtaining the second data, the first VIU processes the second data to obtain the first data. For a specific processing manner, refer to the description of the VIU function. For brevity, details are not described herein again.

Based on different types of automobile parts, manners of obtaining data by the first VIU are different.
